target-arm/kvm: make reg sync code common between kvm32/64

Before we launch a guest we query KVM for the list of "co-processor"
registers it knows about. This is used to synchronize system
register state for the bulk of coprocessor/system registers.
Move this code from the 32-bit specific vcpu init function into
a common routine and call it also from the 64-bit vcpu init.

This allows system registers to migrate correctly when using
KVM, and also permits QEMU code to see the current KVM register
state (which will be needed to support big-endian guests, since
the virtio endianness callback must check for some system register
settings).

Since vcpu reset also has to sync registers, we move the
32 bit kvm_arm_reset_vcpu() into common code as well and
share it with the 64 bit version.

[PMM: just copy the 32-bit code rather than improving it along the way;
 don't share reg_syncs_via_tuple_list() between 32 and 64 bit;
 tweak function names; move reset]
